(Cl. 16S-19) Claims. 1

The invention relates to tools for removing loose material from holes drilled in the earth for oil wells,gas wells, water wells, and the like, and the present invention includes improvements of the invention set forth in my prior U. S. Letters Patent No. 1,786,152, issued December 23, 1930.

The bailing tool of my said U. S. Patent No. 1,786,152v includes a relatively long tubular trepanning drill having walls forming a continuous unobstructed passageway from end to end thereof, there being an enlargement of the passageway intermediate and spaced from the ends thereof, and there being an opening in the side wall o f the tubular trepanning drill intermediate and spaced from the ends thereof and adjacent and communicating with the enlargement. A gate member is pivotally mounted on the tubular member for normally covering the side opening, and a closure member is pivotally mounted on the inner face of the gate member for movement within the enlargement and passageway. 'I'here is a seat in the Walls at the intersection of the enlargement and tubular passageway, and the closure member swings from one position within the enlargement on the seat for entirely closing off the continuous passageway to another position within the enlargement away from the seat permitting free passage of material being bailed through the passageway. The gate member is adapted to be swung away from its normal position closing the side opening to a position in which the closure member is withdrawn from the enlargement through the side wall opening. Latch means are also provided on the gate member for coacting with a. second side opening in the tubular drill to maintain the gate member in closed position during the drillingoperations.

When the bailing tool of my said U. S, Patent No. 1,786,152 is filled, a load of cavingshas been built up in the pipe to the lower end of which the upper end of the trepanning drill is secured,

and the closure member is extended across. the lowerjend of the passageway of the drill, resting on theseat and under the pressure of the cavings sometimes mixed with water and gas which have been collected in the upper pipe.

The gate is likewise subject to this pressure, and in certain instances the pressure of the load collected in the pipe above the closure and gate has been so great that it has jammed the latch or lock on the outwardly swinging upwardly hinged gate,- making it very dilcult to open the latch and swing out the gate and the attached upper pipe of the hailing tool.

'Ihe objects of the present improvements includethe provision of a bailing tool having the general characteristics of the bailing tool of my said U. S. Patent No. 1,186,152, but having an improved structure and arrangement of parts whereby the closure for the passageway of the trepanning drill may be quickly and easily removed, despite any pressure due to the collected load in the upper pipe of the tool.

Further objects of the present improvements include the provision of improved lock means and lock operating and handling means for a door for a side opening in such a bailing tool.

Further objects of the present improvements include the provision of improved bumper means whereby the closure for the drill passageway may retract into a recess at one side of the passageway to permit the passage of .a large rock or other material substantially the size of the pasageway, and to provide for springing back of the closure into the passageway after the rock or other material has passed by.

Further objects of the present improvements include the provision of a hailing tool having the general characteristics of the bailing tool of my said U. S. Patent No. 1,786,152, and having a simplified construction and arrangement of parts whereby the improved bailing tool may be easily andy economically manufactured, used. and maintained.

The foregoing and other objects are attained by the hailing tool and the like, combinations, sub-combinations, and parts, which comprise the present invention, the nature of which is set forth in the following general statement, and preferred embodiments of which together with their mode of use are set forth by way of example inthe following description, and which are particularly and distinctly pointed out 'and set forth in the appended.` claims formingl part hereof.

The nature ofthe present invention may be stated in general termsas including in a hailing tool and the like, a relatively long tubular trepanning drill. member, lthe upper end`of`which is connected to the lower end of a pipe,` and in one side of the tubular member there is formed an opening in which is removably mounted by 'im' proved means a door on `the upper end of which is hinge connected the lower end of a dart or inverted spoon which is adapted. to swing from one position permitting passage of material through the tubular member to another position providing a closure for the passageway ofthe tubular member, the door andthe dart or spoon being removable through the side opening for permitting unloading of the bailing tool.

There is also preferably provided an improved removable key and handle for the door by means of which the lock for the door may be operated and the door and spoon removed together from the side opening.

Preferred embodiments of the improved bailing tool and the parts thereof are illustrated in the accompanying drawing forming part hereofy in which:

Similar numerals refer to similar parts throughout the several views of the drawing.

The improved bailing tool is indicated generally by I and includes a tubular trepanning drill member I I, sometimes known as a shoe, and hav# ing a continuous passageway from end to vend thereof. Within the passage of the tubular drill member II there is operatively mounted an improved automatic closure I2, sometimes known as a' dart or spoon, and which is llocated aboveV the preferably ground angled peripheral lower cutting edge I3 of the 'tubular drill member I I.

There is formed in one side of the tubular drill member Ilan opening I4 which has a flat upper edge I and a curved lower edge I6 and a door indicatedgenerally by I'i' is removably mounted inthe opening I4, the lower end of the closure member I2 having a horizontal hinge connection I8 with the upper end of the door Il'. Within the passageway of the tubular drill member II opposite and above the door I1 there is formed a ledge I8 upon the `which the dart or spoon I2 seats when in the closed position shown in Fig. 2. Opposite the vseat I3 there is formed in the passageway of the tubular drill member II a recess' 2U into which the dart or spoonl2 may swing upwardly when being loaded with cavings asshowninFig-l. y

There is preferably provided a rubber bumping nipple 2l extending from thetop face of the dart or spoon l2 for urging thedart or spoon I2 from the :upper position permitting passage of mate'- rialthrough the passageway 'of-the tubular drill member II as shown in Fig. A1 in full lines and dot-dash lines in Fig. 2 to the position closing the passageway of the tubular drill as shown in full lines in Fig. 2, in which position the dart or spoon I2 carries a load of any cavings or other material which have passed above it in the use of the improved hailing tool i0.

The improved bailing tool I3 is secured as by means of a collar 22 to the lower end of a pipe 23, the internal diameterpf the pipe 23 being substantially equal to the inside diameter oi the tubular drill member I I, and the external diameter of the tubular drill I I and pipe 23 being only slightly less than the internal diameter of the drill hole 24.

The upper end of the pipe 23 is secured as by a coupling 25 to the lower end of a relatively short connecting pipe 26 which is preferably provided with side openings 27 through which excess material may escape. The connecting pipe 2S may be provided at its upper end as shown with a bail 28 which may be connected to a drill line 29, or the connecting pipe may be secured by well known means to a set of jars hungv upon the drill line as may be desired.

As shown and preferably the door VI includes a rear plate 39 and a front plate Si separately secured to each other by screws 32. The upper fiat edge of the rear plate 3B is provided with an upwardly opening notch 33 which receives a hinge tongue 34 extending downwardly from the lower edge of the dart or spoon I2. The hinge tongue 34 has formed therein a hinge bore`35 which receives the hinge pin 36 having ends extending from opposite sides of the hinge tongue 34 and iitting into recesses formed in the front face of the door rear plate 30. The door front plate 3l has a central upwardly extending retaining tongue 31 overlapping the hinge tongue 34 and the hinge pin 36 in the assembled arrangement of the door I1 and the spoon I2.

For providing improved lock or latch means for the door I 'I there is formed a recess 38 in the front face of the door back plate 3B and a rotary latch 39 is located in the recess 38 and overlapped by the door front plate 3i and rear portions of the door back plate 30, and the rotary latch 39 has a forward trunnion 40 journaled in a suitable cylindric opening in the door front plate BI and a similar rear trunnion 4I journaled in a suitable opening in the door back plate 32. The latch plate 39 and its trunnions 49 and 4I have formed therein a square opening 42.

The latch plate 39 is generally cylindric and includes an outwardly extending latch tongue 43 opposite to which it has formed in its periph-'- ery a detent 44. A spring ypressed plunger 45 mounted between the door back plate 30 and door front plate 3l is arranged so that its outer end extends into the detent 44 when the latch plate o 39 is rotated to the latching position as shown in Fig. 2.

The upper end portions 46a and 4Gb of the door back plate 30 extend above the upper edge of the door front plate 3l and are arranged to extend back of and engage the flat 'upper` edge IE of the opening I4 in the tubular drill member II when the door. I'I and spoon I2 are assembled ln the tubular drill member II as shown in Fig. 2, and at the same time the latch tongue 43 is rotated into a retaining groove 41 formed centrally in the lower edgel of the door opening 4 in the tubular drill member Il.l

separable door handle and lock operating key means for holding the door'dur'ing and after removal'and for operating the lock or latch are indicated generally -by 59 and include a stub shaft 5I having a square inner end 52 shaped to t the square opening 42 in the latch plate 33 and its trunnions 4b and el, and from the outer end of the stub shaft 5i there extends an operating handle 53. The stub shaft 5l has formed therein a bore in which is journaled a shank 543 having an enlarged square inner head 55 which is the same size as the squareinner end 52 of the stub shaft 5|. On the outer end of the shank-54 there is secured a turning wing 5S. Accordingly, when, as shown in Fig. 7, the square head 55 has its sides aligned with the square inner end 52' of the stub shaft 5i, both the square head 55 and the square inner end 52 of the stub shaft 5l may be inserted into the 'square opening 42 of the latch plate 39 and its trunnions il and 4l, after which the wing 56 may be turned, turning the square head 55 to the position shown in Fig. 4, thereby securing the handle and lock operating key means 50 in the door l?.

Accordingly, after the improved bailing tool l has been lled with cavings, and elevated from the drill hole, and moved to one side, the square head 55 and square inner end 52 of the door handle and lock operating key means may be inserted into the square opening 42 of the latch plate 3S and its trunnions, the wing 56 may be turned to turn the square head 55 to engage the inner face of the trunnion 4I as shown in Fig. 4, whereupon the handle 53 may be turned to disengage the latch tongue 43 from the groove 4l, and the door l1 and the attached dart or spoon L2 may be moved from the tubular drill member I l permitting the load of material in the bailing tool Hl to drop out. f

When the handle 53 is`P thus locked in the door l1 having the attached dart or spoon I2, these parts become a unitary structure which is bodily removable from the tubular drill member Il.

By the foregoing constructionu and arrangement of the door opening le in the tubular drill member Il, the door Il, the spoon l2, the lock means on the door, and the handle and lock operating key means 55, regardless of the pressure on the spoon l2 when in the closed position as shown in Fig. 2, by a load of cavings, water and possibly gas above the spoon l2, the door il and the spoon I2 may be easily and quickly removed from and through the door opening ld..

The embodiments of the present invention illustrated and described herein are by way of example, and the scope of the present invention is not limited to the same or to the particular details thereof but is commensurate with any and all novel subject matter contained herein which may at any time properly under the United States patent laws be set forth in the claims hereof or originating herein, and the elements of any such claims are intended to include their functional or structural equivalents.
